Learn How to Win Material: Tactical Refutation
This Old Indian Defense puzzle shows a classic tactical refutation in the opening: one active knight is overextended, and the opponent’s back rank and rook placement create a loose tactical target. In positions like this, the key is not long-term strategy but concrete calculation. White can exploit the fact that a central piece is undefended and that a major piece on the edge can become vulnerable to a forcing sequence that wins material decisively.
